Service manual

If you purchased your J-E new then you are entitled to a complete factory installation. Not sure why you didn't get one or why you waited 2 months but what you have already tried may have voided your warranty. Anyway, what is the line voltage coming out of the wall? This is important because you may have to change the transformer tapping position. Failure to have the correct position of the ORANGE wire could cause all kinds of issue. Also, you must set up the Real Time Clock by entering [ENTER] 555 to get into that menu. There is a calibration for the vacuum switch but you should verify the line voltage setting before worrying about that so get back to me when you can. Don

No I understand it was set up for 1~208/230 and yeah, I really didn't want to do it for warranty reasons but we have been trying to get them to come do an install for 2 months and I need it. anyway the time setting fixed it., not sure how that relates to the FRS. All good, thanks for your help.

OK, you need to be more specific about the line voltage because on a J-E the taps are completely different for 208 volts versus 230 volts. As to the FRS issue, the sensor is supposed to trip when the vacuum reaches 13 in of Hg so you need a vacuum meter to see what's going on. Using a DVM you measure across the vacuum sensor and you should see 5VDC until it gets to 13 in. of Hg. At that point the DVM reading should go to 0 VDC. If the vacuum gets to 13 in. and does not trip you can adjust it such that it does. Before I retired I did see a couple of those switches fail but not very often at all. If you get past the vacuum issue then you really should perform the inertia calibration with the highest speed rotor that you have. The service code for that is [ENTER] 311 [ENTER] and then immediately [START]. Push [ENTER] again to get out of the calibration mode. Some rotors only generate 2 values and the higher speed rotors generate 3 values. They should be the same or close to the ones that are on the label when you remove the front cover. If one of the values is out of range then you will get an "R9" diagnostic. Hope all of this helps but the actual line voltage value is a necessity to get the centrifuge set up properly. Don

Thanks, I will measure the actual line voltage and get back to you. You mentioned in an earlier post the pin arrangement on a connector that varies with the power supply. Can you tell me which connector that is and what the various configurations are? Then I will take a look at the vacuum. Cheers, Scott
